Homeless encampments around the country are mushrooming, much to the embarrassment of government officials, many of whom prefer to hear no evil, see no evil. In Fresno, California, a shantytown called “New Jack City” is host to newly poor, unemployed electricians and truck drivers, who share space with drug addicts and the mentally ill who have been homeless for years.

And, thanks to Oprah, Sacramento is famous for its homeless tent city, featuring several hundred people residing in pitched tents bordering the American River. With refuse strewn everywhere, and no potable water or bathroom facilities, this celebrated shantytown is clearly a sanitation risk.
